is “dma2” the ID of your column? you can get the column ids using this query

boards (ids: 123456){
columns{
id
title
type
settings_str
}
}

what type is your column?
it seems like status column and if so, you need to either use the index which is the status color index (you can see in in the settings) or the label text.
so it should look like: {“index”: 0} or {“label”: “teste”}
